Memory Tag Secure Resource Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for monitoring and tracking resource conditions, authenticity, and usage in supply chain management are inefficient, prone to data integrity issues, and lack secure recording capabilities, especially when manual intervention is required or when third-party consumables are used, which can affect warranty validity.
Innovation Solution
The implementation of memory tags with transponder technology that can be attached to resources, allowing for secure storage and transmission of digital data, including usage information, and enabling authentication of genuine products through public/private key encryption, while allowing usage tracking and compliance verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used for monitoring and tracking resource conditions, then ease of operation is maintained, but reliability and data integrity deteriorate
Solution Approach 1:
The memory tag system enables self-service by automatically recording resource conditions, usage information, and environmental parameters without requiring manual data entry. The tag autonomously stores authentication data and tracks resource history, eliminating human intervention while maintaining data integrity through cryptographic security mechanisms.
2Reliability
If secure storage methods are implemented for resource information, then reliability and authenticity verification improve, but device complexity increases
Solution Approach 1:
The patent extracts the complex cryptographic functions from the main resource tracking system and implements them within the memory tag itself. The public/private key pairs are generated and stored within the tag, allowing authentication and data integrity verification to occur at the edge device level, thus reducing the complexity burden on the central system while maintaining high security standards.
3Productivity
If automated tracking systems are deployed, then productivity and efficiency improve, but loss of information increases due to potential data security breaches
Solution Approach 1:
The system performs preliminary actions by pre-generating and storing public/private key pairs within the memory tag before the resource is put into circulation. Authentication data and usage parameters are pre-configured in the tag, enabling secure automated tracking from the outset. This preliminary cryptographic setup prevents information loss by establishing security protocols before any data transmission occurs.
4Measurement precision
If comprehensive monitoring of resource conditions is implemented, then measurement precision improves, but device complexity and cost increase
Solution Approach 1:
The memory tag is designed as a universal platform that can monitor multiple resource conditions (temperature, usage, location, environmental parameters) through integrated or attached sensors. The single memory tag device serves multiple functions by storing data from various sensor types, eliminating the need for separate complex monitoring systems for each parameter and reducing overall system complexity while maintaining comprehensive measurement precision.
Data Source
AI summary
A system for tracking resource parameters includes a resource having an associated memory tag; a parameter sensing element sensing a parameter of the resource; and a memory tag reader/writer. The system is configured to store information gathered from the parameter sensing element on the memory tag.
